Ubuntu has come under a decent amount of flack over the past few months, particularly over their decision to use the 'Dash Search' to return results from Amazon by default in their most recent release.

....Kubuntu is my choice, firsly, Canonical's stupid design and developing descicions are not there as Kubuntu has been put into another entities hands, Blue Sytems, and KDE is very customizable, has a fullscreen mode, e.g. when running full screen apps like a steam game , a lot of components of the window manager and Desktop enviroment are turned of. This is much better over the dully complying Compiz and Unity, ugh, well there's always 900+ distros to try out, rather not waste my time on Ubunity 12.10 hyper HD remix
